This map shows the projected change in mean precipitation for 2046-2065, with respect to the reference period of 1986-2005 for RCP4.5, expressed as a percentage (%) of mean precipitation in the reference period. The median projected change across the ensemble of CMIP5 climate models is shown....

Statistically downscaled multi-model ensembles of projected change (also known as anomalies) in minimum temperature (°C) are available at a 10km spatial resolution for 1951-2100. Statistically downscaled ensembles are based on output from twenty-four Coupled Model Intercomparison Project Phase 5...

Statistically downscaled multi-model ensembles of projected change (also known as anomalies) in total precipitation are available at a 10km spatial resolution for 1951-2100. Statistically downscaled ensembles are based on output from twenty-four Coupled Model Intercomparison Project Phase 5...

Seasonal and annual trends of mean surface air temperature change (degrees Celsius) for 1948-2016 based on Canadian gridded data (CANGRD) are available at a 50km resolution across Canada. Temperature trends represent the departure from a mean reference period (1961-1990). CANGRD data are...

This map shows the projected average change in mean temperature (°C) for 2081-2100, with respect to the reference period of 1986-2005 for RCP8.5. The median projected change across the ensemble of CMIP5 climate models is shown. For more maps on projected change, please visit the Canadian...

This map shows the projected change in mean precipitation for 2046-2065, with respect to the reference period of 1986-2005 for RCP2.6, expressed as a percentage (%) of mean precipitation in the reference period. The median projected change across the ensemble of CMIP5 climate models is shown....

The Canada’s Changing Climate Report (www.changingclimate.ca/CCCR2019), led by Environment and Climate Change Canada, is about how and why Canada’s climate has changed and what changes are projected for the future. Datasets supporting the results produced for the Canada’s Changing Climate report...

High-resolution statistically downscaled climate indices relevant to climate change impacts in Canada are available at a 10 km spatial resolution and an annual temporal resolution for 1951-2100. The climate indices are based on model projections from 24 global climate models (GCMs) that...

The recent (2017) spatial patterns of zooplankton communities in 73 Québec lakes distributed over an 800-km SW-NE gradient, spanning a wide range of water quality and climate. Results were published in a scientific article that can be found here: https://doi.org/10.1139/cjfas-2020-0139

This dataset is part of the International Atomic Energy Agency (IAEA) Global Network of Isotopes in Precipitation (GNIP) project and contains the total monthly precipitation quantity in millimeters collected on the roof of the National Hydrology Research Centre in Saskatoon, SK and its stable...

This dataset consists of CLASS (Canadian Land Surface Scheme) simulations for ALMIP2 (AMMA [African Monsoon Multidisciplinary Analysis] Land Surface Model Intercomparison Project, Phase 2). The results of the intercomparison is published in the paper "Streamflows over a West African Basin from...

The Canadian Centre for Climate Modelling and Analysis (CCCma) Earth System Grid Federation (ESGF) Dataset provides the Environment and Climate Change Canada (ECCC) node on an internationally-coordinated system of climate model data dissemination developed specifically for the World Climate...

The data consists of temperature indices based on homogenized daily maximum and minimum temperatures at 338 locations across Canada, and of precipitation indices based on adjusted daily rainfall, daily snowfall and daily precipitation amounts at 463 locations across the country. These indices...

The data consist of homogenized daily maximum, minimum and mean surface air temperatures for more than 330 locations in Canada; adjusted daily rainfall, snowfall and total precipitation for more than 460 locations. The data are given for the entire period of observation. Please refer to the...

The Alberta foothills are a primary source of spring runoff into the prairie regions to the east. For this reason, precipitation accumulations in the foothills are vital to prairie water resources. The Foothills Orographic Precipitation Experiment (FOPEX) was initiated in 2002 to study the...

Persistent, large-area droughts are among Canada’s costliest natural disasters, having major impacts on sectors such as agriculture, industry, forestry, recreation, human health and society, and ecosystems. This dataset provides 50 km gridded, 12-month Standardized Precipitation...

This paper presents an analysis of observed and simulated historical snow cover extent and snow mass, along with future snow cover projections from models participating in the 6th phase of the World Climate Research Programme Coupled Model Inter-comparison Project (CMIP6). Where appropriate, the...

This series includes maps of projected change in mean precipitation based on CMIP5 multi-model ensemble results for RCP2.6, RCP4.5 and RCP8.5, expressed as a percentage (%) of mean precipitation in the reference period. The median projected change across the ensemble of CMIP5 climate models is...
